udev_new() allocates a new udev context object and returns a pointer
to it. This object is opaque and must not be accessed by the caller
via different means than functions provided by libudev. Initially,
the reference count of the context is 1. You can acquire further
references, and drop gained references via udev_ref() and
udev_unref(). Once the reference count hits 0, the context object is
destroyed and freed.
